How to Maintain Your System after Air Duct Cleaning

Regular air duct cleaning should take place between three and five years, depending on certain factors such as the type of system and how often it is used. However, homeowners can maintain the integrity of the system and prolong the need for more frequent cleaning by performing maintenance.

Prevent Contamination

When it is time to replace air duct filter or filters, it is recommended to ensure that you use manufacturer recommended filters. These are optimized for your particular system and usually will fit better than generic filters. If the filter appears to be full or clogged when changing it is a good indicator of the system being excessively contaminated and you may need to change the filter more often. You should make sure that every filter gap has a filter installed.

When emptying the drip pans, it is a good idea to clean them regularly but at least once a year. You should also ensure that before any remodeling or renovation takes place, all vents are sealed off and the system is not run until the work is completed and the resulting dust and debris cleaned away.
It is also good practice to ensure that your vacuum cleaner bag and filter are regularly changed. Full canisters can emit a great deal of dust into the air which enters the ventilation. Cleaning dust and debris and sealing it into a vacuum bag should prevent it from re-entering the system.

Prevent Moisture

The humid environment of your air duct system can be a prime atmosphere for mold, mildew and bacteria to flourish. This can significantly compromise the indoor air quality home residents are breathing. This can not only cause health difficulties for those with asthma or prone to allergies but can create a musty or stale odor throughout the home.

Regularly inspect your system for any leaks or damage which can create condensation. Any air duct repair should be completed as quickly as possible to minimize damage.
